碩士 === 國立臺灣師範大學 === 應用電子科技學系 === 102 === In the paper we present a novel adaptive multicycle Discontinuous Reception (DRX) scheme which dynamically adjusts the DRX parameters according to the base station’s perceived traffic intensity and specific Quality of service (QoS) for Long Term Evolution (LTE) networks. It is a table-driven method which off-line pre-establishes the table of the optimal DRX parameters based on a theoretical analysis approach. At runtime, the DRX parameters of each user equipment (UE) can be determined optimally with a simple table lookup rapidly without spending much computational time. We conducted simulations to compare the performance of our proposed multi-cycle DRX scheme with that of the conventional DRX scheme. The results demonstrate that our approach can effectively improve both the user-perceived service quality and power saving efficiency according to the current traffic intensity and QoS requirements, and thus enhances the overall system performances.
